METALLIC SOCKET-CONNECTION FOR STONE COPING.

SPECIFICATION forming part of Letters Patent No. 380,710, dated April 10, 1888.

Application filed June 9, 1887. Serial No. 240,843. (No model.)

To aZZ whom. it may concern.-

Be it known that I, WILLIAM WILLIAMs, a citizen of the United States, residing at Hunt ingdon, in the county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Socket- Connections for Stone Coping; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

In the preparation of coping, curbing, and panels in such stone-work, great care must be exercised in jointing the ends of each piece, and much time is spent in setting the work.

The special object of my invention is to 0bv1ate,and provide a substantial remedy against, the annoying defect of coping becoming detached and falling apart, as is the case so often now, and reduce the cost inateriallyin cutting and setting the work in place with the use of the1 socket and not dressing the ends of the m1 s.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a detached sectional side view of the various pieces of stone which usually make up a line of coping or curbing. Fig. 2 exhibits a vertical side elevation of the detached pieces in a conjoined state with the use of the socket. Fig. 3 shows a perspective transverse view of the socket, indicating apertures f f, the appendage-brace 0 c and leaden bottom 6. Fig. 4 exhibits the socket E, in perspective half-sectional side view, attached to the post F by means of appendage andindependent half-wedge tenons and lead filling; and in Fig. 5 the socket is shown in a vertical transverse form, indicating an interjacent filling of lead between the stone and metal substance, leaden bottom, and setscrews, all for the purpose hereinafter described.

The post A and stone rails 13 B, as shown at Fig. 1, are in a disconnected form, the post A being unprovided with sockets. The adjacent stone rails 13 B show unwrought ends or of, as I propose using them in constructing coping.

The post 0, Fig. 2, is provided with metallic sockets a a for the reception and support of rails B B, which are shown joined to post G, as indicated at D D, with the ends of unwrought pieces extending into the sockets a a to or near dotted lines I) b. The set-screws if b, inserted in the rails D D, prevent a detachment of parts.

E shows the socket with one open end, indicating aperturesff in the rear end, through which a filling of lead or soft metal is had between the half-wedge tenons, to secure the socket E to the post F in the manner shown.

The leaden strata 6, arranged on the bottom of the socket, prevents the stone and metal from contacting and fracturing the former. The brace 6 re enforces the socket against heavy strain produced by the weight of the stone rails D D. The dowel 6 attached to the brace e, is let in the post, as shown at F, (at) The socket E, at Fig. 4, is cut in half, side view, indicating the half-wedge tenons n n, attached to the socket E, purposely formed as shown, and adapted to fit the dovetail grooves cut in the post F for their reception. The independent half-wedge tenons a n are not attached to the socket E, but in form are like a If, to fit in the dovetail grooves in the post.

To secure the socket E to the post F when the half-wedges are arranged in the grooves in the post, the filling of lead a n is made through the apertures f f, and when densified a lateral pressure will be produced against the halfwedges n n 92 n .interlocking the socket to the post, as shown. The'interjacent backing of lead, at m, which skirts the back of the socket, prevents the parts from contacting and rusting the stone. The socket at Fig. 5 is shown in a transverse form, indicating an interjacent filling of lead, 3 s s, skirting the stone H, to be solidified to a degree to keep the parts in contact and exclude water. The screws 8 s, inserted in the stone H, prevent the pieces from disconnecting, substantially for the purpose set forth and described.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. In a coping or curbing, the combination, with panels having unwrought ends a a, of

the intermediate posts, 0, provided with metallic sockets a a, for the reception and support of the adjacent pieces of stone, and jointed together with soft metal, substantially as described.

2. The combination, with a stone coping, of the metallic socket E, having apertures f f, leaden bottom 6, brace e, and dowel a, substantially combined for the purpose specified.

tween half-wedges, substantially for the pur- 15 pose set forth.

4. The combination, with a stone coping, of the socket E, having an interjacent stratum of lead filling, s s 8 and set-screws s 8", substantially for the purpose set forth, as de- 20 scribed. v

In testimony whereof I affix my signature in presence of two witnesses.
